DETAILED DESCRIPTION

FIG. 1 depicts a general brassiere 10 comprising two breast cups 11 and two underwire regions 12, which will be discussed in further detail in relation to the present invention.

The present invention relates to cushioned underwire casings and their methods of manufacture. The cushioned underwire casings are designed to be attached to the underwire regions 12 of a brassiere 10 and to receive an underwire, in order to provide shape and support for the breast cups 11. In this regard, the present invention also relates to a cushioned underwire, a breast cup, and a brassiere that incorporate a cushioned underwire casing according to the present invention.

FIG. 2 shows a perspective view of a breast cup 11 comprising an underwire region 12 with an attached cushioned underwire casing 100 in accordance with a first embodiment of the invention. In FIG. 2, the breast cup comprises two fabric-foam laminate layers 13, 14, comprising an inner foam layer 13 with a fabric layer 13′ laminated to the surface that contacts a wearer of the brassiere and an outer foam layer 14 with a fabric layer 14′ laminated on the surface that faces away from a wearer of the bra. However, any layer arrangement may be used comprising one or more layers of fabric, foam or fabric-foam laminates.

The cushioned underwire casing 100 of FIG. 2 comprises a cushioning material 160 and a structure 170 that captures the underwire 150 and the cushioning material 160, as will be described in greater detail with reference to FIG. 3. The cushioned underwire casing 100 is preferably attached to the underwire region 12 by sewing it to the breast cup 11 along sew lines 190. The cushioned underwire casing 100 casing is sewn to the side which faces the wearer, with the cushioning material 160 being positioned between the wearer and the channel for receiving the underwire 150 to provide cushioning of an inserted underwire 150. It is preferable to attach the cushioned underwire casing to the breast cup before inserting an underwire 150, because it makes the sewing step easier.

The cushioning material 160 can be any suitable cushioning material, by way of non-limiting example it could be foam, gel, silicone or thermoplastic rubber, or a combination of suitable materials.

In FIG. 2, the cushioned underwire casing that is attached to the underwire region 12 of the breast cup 11 can be any of the cushioned underwire casings 100, 200, 300, 400 of the present invention, and not just that of the first embodiment 100, as will become apparent from the detailed description of the cushioned underwire casings 100, 200, 300, 400 and their methods of manufacture.

FIG. 3 illustrates in greater detail the cushioned underwire casing 100 of the first embodiment and its method of manufacture. The structure 170 for the cushioned underwire casing 100 is preferably a fabric structure. The structure 170 comprises a body 171 having a channel 172 for receiving the underwire 150 and a wing member 173 integral with and extending from the body 171. The wing member 173 is configured to be folded around (as shown by arrow A) a portion of the body 171 for capturing the cushioning material 160 positioned between the body 171 and the wing member 173, as will be described in detail in relation to a method for manufacturing the cushioned underwire casing 100.

A method for manufacturing the cushioned underwire casing comprises, with reference to part (b) of FIG. 3, positioning the cushioning material 160 over the outside of the body 171 of the structure 170, folding the wing member 173 around the cushioning material 160 (as shown by arrow A) to capture the cushioning member 160 between the body 171 and the wing member 173. Preferably, the cushioning material is fixed to the body 171 of the structure 170 by any suitable means. By way of a non-limiting example, if the cushioning material 160 is foam, the cushioning material 160 can be attached to the body 171 by way of heat press molding, preferably with adhesives added, or if the cushioning material is gel, silicone or thermoplastic rubber, the attaching can be accomplished by way of injection moulding. As illustrated in FIG. 3, the cushioning material 160 is positioned on the outside of the body 171 and is captured between the body 171 and the wing member 173.

Turning to part (c) of FIG. 3, the cushioned underwire casing 100 is sewn to the breast cup 11 along stitches lines 190 (for clarity, the breast cup 11 is not illustrated) to attach the cushioned underwire casing 100 to the breast cup 11, as well as attaching the wing member 173 to the body 171. The underwire 150 is then inserted into the channel 172 of the body 171. Although it is preferable to insert the underwire after the cushioned underwire casing 100 has been sewn to the breast cup 11, the underwire 150 could be inserted before sewing. The finished cushioned underwire casing 100 with inserted underwire 150 is depicted in part (c) of FIG. 3.

As shown in FIG. 3, parts (b) an (c), the cushioned underwire casing preferably comprises a film layer 180. In this embodiment, a film member is attached to the wing member 173, on the side of the wing member 173 that contacts the cushioning material 160. The wing member 173 with attached film 180 is then folded in the direction of arrow A to capture the cushioning material between the body 171 and wing member 173, with the film 180 positioned therebetween. The film 180 may be advantageous where the cushioning material 160 is greasy, as it will prevent the greasy cushioning material 160 showing through the wing member 173 especially if the wing member 173 is made of fabric.

FIG. 4 shows a second embodiment of a cushioned underwire casing 200 of the present invention. The cushioned underwire casing 200 is substantially the same as that of the first embodiment, with like reference numerals used to indicate like parts. The difference between the cushioned underwire casing of the second embodiment 200 and that of the first 100 is in the structure for capturing the underwire and cushioning material. In the second embodiment, the structure 270 comprises two protrusions 274 that extend from the body part 271. Preferably, the protrusions 274 are integral with the body part and are formed when the structure is woven. The protrusions 274 are sized and shaped such that the cushioning material 260 can be positioned between the protrusions 274, as shown in parts (b) and (c) of FIG. 4. As with the first embodiment, the cushioning material 260 is preferably attached to the body 271. The wing member 273 is folded around the protrusions 274 and the cushioning material 260 to form the cushioned underwire casing 200. The protrusions 274 provide the cushioned underwire casing with a more rectangular and less bulging cross-section than that of the first embodiment shown in FIG. 3. The protrusions 274 may be of a lower height than the cushioning material 260, such that the cushioning material extends above the protrusions 274, so that the protrusions 274 are not felt by the wearer. As illustrated in FIG. 4, the cushioning material 260 is positioned on the outside of the body 271 and is captured between the body 271 and the wing member 273.

The cushioned underwire casing 200 is sewn to a breast cup 11 along sew lines 290 to attach the casing 200 to the breast cup 11 and also preferably to attach the wing member 273 to the protrusions 274. Thus, each sew line 290 preferably passes through the breast cup 11, the wing member 273 and one of the protrusions 274. The underwire 250 is then inserted into the cushioned underwire casing 200, as shown in part (c) of FIG. 3. As with the first embodiment 100, a film 280 may also be provided.

FIG. 5, part (c), shows a third embodiment of a cushioned underwire casing 300 comprising an underwire 350 in accordance with the present invention. The cushioned underwire casing 300 is substantially the same as that of the second embodiment 200, but the structure 370 comprises a single protrusion 374 extending from the body 371 of the structure 370. As with the second embodiment 200, the protrusion 374 is preferably integral with the body 371 and is formed when the structure 370 is woven. As can be seen from part (c) of FIG. 5, the cushioned underwire casing 300 of the third embodiment has a more sloped cross-section, sloping from a higher side to a lower side. Preferably, the higher side is sewn to the innermost edge of the underwire region 12 of the breast cup 11 and the lower side is sewn to the outermost edge of the underwire region 12, such that the visible edge (i.e. the outermost edge) of the cushioned underwire casing 300 when the brassiere 10 is worn is the thinnest, reducing the visible bulk of the cushioned underwire casing 300 whilst also reducing the bulging that results from the cushioning material 360. As with the third embodiment, the sewing of the casing 300 to the breast cup 11 preferably also sews the wing member 373 to the protrusion 374. As with the first 100 and second 200 embodiments of the cushioned underwire casing, a film 380 can also be provided. As illustrated in FIG. 5, the cushioning material 360 is positioned on the outside of the body 371 and is captured between the body 371 and the wing member 373.

Although FIG. 5 illustrates a single protrusion extending on the left side only, i.e. the side that is further away from the wing member, a variation is that the single protrusion extends on the right side only, i.e. the side that is closer to the wing member, though such variation is not shown in the figures.

A fourth embodiment of the cushioned underwire casing 400 of the present invention is shown in part (c) of FIG. 6, where the casing 400 includes an underwire 450. In the fourth embodiment, the structure 470 is a three leafed structure comprising three integrated leaves 471 a, 471 b, 473. Preferably, but not necessarily, the structure 470, before incorporation into the cushioned underwire casing 400, has a T-shaped cross-section as seen in part (a) of FIG. 6. The method of manufacturing the cushioned underwire casing shown in part (c) of FIG. 6 is now described with reference to part (b) and (c) of FIG. 6. With reference to part (b), a cushioning material is attached to a first leaf 471 a of the structure 470. The attachment may be achieved as described in relation to the first embodiment. Each leaf has an end that is attached to the other leaves and a free end. The method comprises bringing the free ends of the leaves together, as shown by arrows B and C in part (b). The leaves are brought together to form, from the first 471 a and second leaves 471 b, a body 471 upon which the cushioning material is attached, and a wing member which is the third leaf 473. The wing member or third leaf 473 is folded around the cushioning material 460 to capture the cushioning material 460 between the body 471 a, 471 b and the third leaf 473.

The order of attaching the cushioning material 460 to the first leaf 471 a and bringing the leaves together can be changed without departing from the scope of the invention. For example, the free ends of the first and second leaves 471 a, 471 b can be brought together (as shown by arrow C) to form the body 471, and the cushioning material 460 can then be attached to the outside of the body (i.e. to the first leaf 471 a). Thereafter, the third leaf 473 can be folded around the cushioning material 460 in the direction of arrow B to capture the cushioning material 460 between the body (the first leaf 471 a of the body 471) and the third leaf 413.

In addition, a film 480 may be provided. If provided, it is attached to the third leaf 473 prior to the free end of the third leaf 473 being brought together with the free ends of the first and second leaves 471 a, 471 b. The film 480 is attached to the side of the leaf that contacts the cushioning material to provide a barrier against a greasy cushioning material, as described previously.

As illustrated in FIG. 6, the cushioning material 460 is positioned on the outside of the body 471 and is captured between the body 471 and the wing member 473.

As with the previous embodiments, the cushioned casing for an underwire is sewn to an underwire region 12 of a breast cup 11 along sew lines 490. The sew lines 490 preferably pass through all three free ends of the leaves 471 a, 471 b, 473 on one side of the cushioning member 460 and the joined leaves on the other side of the cushioning material 460. Thus, the sewing of the casing 400 to the breast cup 11 also results in attaching the free ends of the leaves together to form a secure underwire channel 472 and to securely capture the cushioning material between the body 471 and third leaf or wing member 473. The underwire 450 is then inserted into the cushioned underwire casing to complete the cushioned underwire.

Although the protrusions have been described and are illustrated with respect to the second and third embodiments only, the fourth embodiment could be provided with one or more protrusions also, if desired.

As specified above, the film 180, 280, 380, 480 is an optional feature of all four embodiments of the cushioned underwire casing 100, 200, 300, 400. The film 180, 280, 380, 480 is flexible and is preferably a plastic film, or more preferably a polyurethane film.

Although the cushioning material 160, 260, 360, 460 is preferably attached to the outside of the body 171, 271, 371, 471 of the structure 170, 270, 370, 470 in all of the described embodiments, the cushioning material could instead be placed on the outside of body without attachment, the cushioning material being held in place by being captured between the body 171, 271, 371, 471 and the wing member 173, 273, 373, 473.

Furthermore, as detailed above, the cushioned underwire casing 100, 200, 300, 400 is preferably sewn to the breast cup 11 before the underwire 150, 250, 350, 450 is inserted into the casing. However, if desired, the underwire 150, 250, 350, 450 can be inserted into the casing 100, 200, 300, 400 prior to the sewing of the casing to the breast cup 11.

Although the preferred embodiments describe the cushioned underwire casing 100, 200, 300, 400 being sewn to the breast cup 11, other suitable attachment means can be provided to attach the cushioned underwire casing 100, 200, 300, 400 to the breast cup 11 and to attach the wing member 173, 273, 373, 473 to the body/protrusions 171, 274, 374, 471, such as adhesive.

Furthermore, the cushioned underwire casing 100, 200, 300, 400 need not be attached to the breast cup 11 in the same step as attaching the wing member 173, 273, 373, 473 to the body/protrusion 171, 274, 374, 471. If desired, the wing member 173, 273, 373, 473 can be attached to the body/protrusion 171, 274, 374, 471 before the cushioned underwire casing 100, 200, 300, 400 is attached to the breast cup 11.

The structure 170, 270, 370, 470 is preferably a fabric structure. The integrated structure 170, 270, 370, 470 is preferably woven to produce a body 171, 271, 371 integral with a wing member 171, 271, 371 or three integrated leaves 471 a, 471 b, 473.
